There have been several reports that tensions are high on set between Glee co-stars Naya Rivera and Lea Michele but the stories have been conflicting.

Sources say Rivera was getting tired of Michele’s diva-like antics, such as making everyone wait until she was ready to shoot scenes, and told producers. When Michele found out, a confrontation transpired and she stormed off set.

Other sources told TMZ Michele and Rivera didn’t even film together on the day that all reportedly happened this week, and it was Rivera who was kicked off of set for unknown reasons.

Sources told HollywoodLife about Rivera, that she “showed up to the set in really bad shape — she’s been acting more and more erratically on set. She went off on one of the producers on the show and they got really upset with her and it escalated from there.”

Rivera is undeniably going through a difficult time in her personal life, as her rapper fiancé Big Sean recently called off their engagement.

There were reports that he had been unfaithful, but his rep said in a statement, “Sean wishes Naya nothing but the best and it is still his hope that they can continue to work through their issues privately.”
